Received Date: 20 November 2012

摘要: "侵蚀热点"的存在会对整个海岸资源造成严重的损失,尤其是对海滩养护工程效果造成不良影响,是海滩养护研究的重点。以北戴河西海滩海滩养护工程为例,结合工程后定期的剖面监测数据,确定了养护工程后西海滩"侵蚀热点"的位置,通过数值模拟和物理模型试验对于侵蚀热点的成因进行了分析研究,以期能够对以后的海滩养护工程提供参考。

Abstract: The study of "erosional hotspots" has become a hot topic for beach nourishment projects all over the world, since they might cause serious loss of coastal resources, and bring negative effect on beach nourishment projects. In this paper, using the beach nourishment project at the west Beidaihe beach as a case, the authors studied the erosional hotspots of west Beidaihe beach after nourishment through numerical modeling and physical model tests. Coupled with the monitoring data in different periods after the project, the locations of erosional hotspots at the west Beidaihe beach have been discovered. The origin of erosional hotspots was discussed as well in this paper so as to provide a technical case for reference by other beach nourishment projects.
